I was about an hour into a discharge test of my lithium system and the BMV-712 shut it down about an hour later (see chart) because of high temperature. The ambient temperature was about 70F. The battery bay ambient temperature was about 64F. I had a constant load (convection microwave set to Mix High 325 drawing about 1300W). The internal temperature of the batteries was 70F, according to my Bluetooth utility, at the end of the test. The BMV-712 temp input comes from the battery temp sensor that's connected to the POS battery terminal.
Why would I get this elevated temperature from the battery post while internal battery temperture is staying cool. TIA...
